APPARATUS FOR LOADIING AND UNLOADING W'AGONS.

SPECIFICATION forming part of Letters Patent No. 270,159, dated January 2, 1853.

Application filed October 6,1882. (NomodeL) To all whom it may concern i Be it known that I, SILAS VAN PAT'IEN, of Dnanesburg, in the county of Schenectady and State of New York, have invented certain new and usefulImprovements in Apparatus for Loading and Unloading Wagons, of which the following is a full, clear, and exactdes'cription.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all'the figures.

Figure l is a plan view of my improvement, parts being broken away. Fig. 2 isa side elevation of the same. Fig. 3 isasectionalend elevation ofthe same, taken through the line mm, Fig. 2. Fig. 4 is a sectional side elevation of a part ofthe same. Fig. 5 is a sideelevation, partlyin section, ofthe forward partof tongue. Fig. 6 is a sectional plan view of a part of the derrick, taken through the line yy, Fig. 2. Fig. 7 isa sectional sideelevation of a part of the derrick.

The object of this invention is to improve the construction of the apparatus for loading and unloading wagons, for which Letters Patent No. 251,659 were issued to me December 27, 1881, in such a manner as to make it simpler in construction, more convenientin operation, and more readily controlled.

The invention consists in the combination, with the tongue, the slotted block attached'to the rod sliding in the tongue, and the brakevrod, of an elbow-lever, and a bend formed upon the shaft of the brake-lever, whereby the said sliding rod can be readily locked and unlocked. The extensionrod sliding in the tongue is strengthened by a bar attached to the sliding block and to the band attached to the U- shapcd end of the extension-rod. The band attached to the U-shaped end of the extensionrod is made with a flange upon its upper side and a pin at its lower side to adaptit to serve as a stop for the neck-yoke ring. The derrick is made curved and tubular, and is provided with a pulley at its upper end to adapt it to receive the hoisting-rope. The socket-rings in which the derrick turns are provided with bushings to adapt them to receive differentsized derricks. With the rear axle of. the wagon is connected a clamp operated by a rod projecting at the side of the wagon-body to grasp the hoisting-rope and hold the load when partly raised and allow the apparatus to be readjusted. To the sand-board are pivoted guide-pulleys to cause the hoisting-rope to work freely when the wagon is cramped, as

will be hereinafter fully described.

A represents the rear wheels, B the forward wheels, 0 the rear axle, D the forward axle, E the rear bolster, F the forward bolster, G the sand-board, H the rear hounds, I the forward hounds, J the reach, and K the body, of an ordinary wagon. L is the tongue, which is connected with the forward hounds, I, by a bolt, M, in the ordinary manner. i

In the upper side of the tongue L is formed a longitudinal groove, in which is placed a rod. N. The rod N forms an extension-tongue, and its forward end is bent downward and rearward into U-form, and has a ring-band, 0, attached to it, through which the end of the tongue L passes when the rod N is in its normal position. The forward part of the rod N is kept in place in the groove of the tongue L by a clip, P, the arms of which pass. through a yoke, Q, placed beneath the tongue L, and have nuts screwed upon them.. The groovein the tongue L is made dovetailed in shape, and

is faced with metal to prevent wear, and into it is titted a dovetailed block, R, attached to or formed upon the rear end of the rod N, so as to prevent the rear end of the said rod from rising out of the said groove as the said rod slides forward and backward. The doubletree is designed to be secured to the block R by a bolt, S, and hammer-strap T, as indicated in Fig. 4. The rear part of the block it projects upward, and has its rear upper corner rabbeted, and a slot or notch formed in the shoulder of the said rabbet to receive a pin, U, formed upon orattached to the angle of the elbow-lever V, which is-made double, and has its lower arm pivoted, to the side of the tongue L. The lower arm of the elbow'lever V projects below the tongue L, and to its end is attached the forward end of a link, W, which forward end of the rod Y, which passes back beneath the reach J, passes through the rear too axle,'O, and is attached to the brake-bar Z.

The brake-barZ is supported by and slides lorward and back upon arms a, attached to the rear parts of the side-boards of the Wagonbody K, and is held back to keep the brakeshoes b out of contact with the wheels A by springs a, placed upon the said arms a.

Theupper arm of the elbow-lever V projects back above the rear'end of the tongue L, and has a short slotformed in it to receive the bend d of the shaft 6, which works'in the eyes ofthe eyebolts or other suitable bearings attached to the forward side of the forward bolster, F.

Upon the end of the shaft 0 is formed or to it is attached a lever, f, which projects upward at the side of the wagon-body K, into such a position that it can be readily reached and operated by the driver with his foot. The bend d and the lever f stand about at right angles with each other. With this construction, when the lever fis in-an upright position and a rearward pressure is applied to the tongue L, the said pressure will be sustained by the bend d of the shaft 6 and the upper arm of the elbow-lever V, so that the wagon can be backed without applying the brake. rearward pressure is applied to the tongue L and theleverfis pressed forward at the same time, the bend d and the upper arm of the elbow-lever V will be pressed downward out of line, and the rearward pressure upon the tongue and the forward pressure upon the le Yer will act together to apply the brake. The brake can be applied by means of the leverf alone when desired, and by moving the said lever forward through the arc of a quadrant the bend d will take a vertical position, and the brake will be locked against the wheels, and the extension-rod N of the tongue L will be free to move forward and back without affecting the brake. Y

The rear end of the slotted block R is inclined, as shown in Figs. 3 and 4, so that when attached the end of a rope, h, which passes through a guide-hole between the bolster F and the sand-board G, passes around a guidepulley, '5, pivoted to a support attached to the brake-barZ, passes around a guide-pulley, j, pivoted to a support formed upon or attached to the bar 70, secured to the wagon-body K or bolster E, passes'through the hollow curved derrick l, pivoted to the said bar k, passes around a pulley, m, pivoted to supports attached to the upper end of the derrick l, and has a hook, at, or other suitable grapple attached to its end. The lower part of the derrick 1 passes through a ring, 0, formed upon the upper end of the bar 70, and the lower end of the said derrick l enters a ring, 19, formed upon the lower part of the said bar it and rests upon aninterior shoulder, g, formed upon or attached to the lower part of the said ring. The shoulder q should be made of steel or other suitable material to preventitfrorn being worn by the end of the derrick I. The bar is strengthened in. position by braces r, the upper ends of which are secured to lugs formed upon the opposite sides of the ring 0, and their lower ends are attached to the side-board of the wagon-body K. The interior of the socket-rings 0 p is made large, and into the said rings are fitted bushings 3, which are kept in place by set-screws 4 or other suitable means, so that derricks of ditferentsizes can be used. as the weight of the loading to be handled may require.

When heavy material is to be loaded upon or unloaded from the wagon the rope h is drawn out, the grapple n is attached to the said load, and the leverfis operated to release the block R of the sliding extension-rod L. The horses are then driven forward, drawing forward the rod L, block R, and rope it until theload has been raised above the upper edge of thewagon-body K, when the derrick lis swung around to bring the load over or away from the wagon, and the horses are hacked to lower the load into the desired place. When theload is very heavy the rope It can be passed through a pulley-block, s, and its end attached to an eye, 75, formed upon the derrick 1, near its upper end, as illustrated in Fig. 3. In this case it will be necessary to move the extension-rod L out and in two or more times in raising the load upon or lowering it from the wagon. To enable this to be done the rope h, where it passes through the rear axle, O, is clamped against a stationary block or support, to, attachedto the said axle by a lever, 12, pivoted to a support attached to the axle and operated by a rod, 10, attached to its outer end, the said rod passing out through a keeper attached to the bottom of the wagonbody K.

The end of the rod w projects at the side of the wagon-body K, so that it can be conveniently reached and operated. v

To the forward side of the sand-board Gr, upon each side of the hole through which the rope it passes, is pivoted a pulley, as, so that the said rope will work freely when the wagon is cramped.

When the apparatus is to be used for handling heavy loads the rod N can be stifiened and strengthened by a bar, 3 placed upon the upper side of the tongue L. The forward end of the bar 3 has a pin, 2, formed upon or attached to it, which passes through a hole in the flange 5, formed upon the upper part of the band 0. The rear end of the bar y is secured to the forward end of the block R by a bolt, 1, and nut. When light loading is to be handled the bar y need not be used.

The band 0 is placed in an inclined position, and has a pin, 2, attached to or formed upon its lower side to adaptit to serve as a stopfor {)he llgleck-yoke ring when backing and holding Having thus fully described my invention, I I stantially as herein shown and described, to
